EDGA JAMES,

V AI IToMoBI LE-nrtivn v or Lmoomvtro v, NORTHLCAROLINIAJ i To all whom2'25 may concern: I j t Be it known thatl, EDGAR JAMES, a citi- Zen ofthe, United States, residing at Lin- 1 colnton,in the countylof'lnncolnand State of North Carolina, have i11vented;cert,ain new and usefulImprovements 1n Automobile-Drives, of which the following; is aspecification: I l p, I,

Thisinvention relates to lmprovements 1n driving gearingfor automobilewheels and the like, and more particularlyto Tdriving gearingparticularly adapted for useon the driving wheels of .a 'motor truck.

An important object of the invention is to provide a form of gearingfor" truck wheels wherein the driving is balanced and there is notendency to side thrust in one direction.

A further object of the inventionis to provide an improved internal geardrive for motor trucks and the like.

Other objects and advantages of the invention will become apparentthroughout the following description. These objects I have attained bythe combination and arrangement of parts shown in the accompanyingdrawings, wherein for the purpose of illustration is shown a preferredembodiment of my invention, and wherein, V 1

Figure 1 is a plan View of the rear end of a truck showing my inventionapplied an axle constructed to allow the application of my invention tomotor trucks.

Referring now more particularly to the drawings, the numeral 16indicates the body frame of a truck having secured thereto in anysuitable manner the axle 17 to which in turn is secured the usualdifferential 18 having extending from each side thereof shafts 19. Thedifferential used is preferably that shown in my copending application,Serial No. 305,725 filed June 21, 1919, of which this application is adivision, although not necessarily restricted to this construction. Itwill be noted that in the construction of my invention the drive shafton the ends of the ranged to one side thereof,

s is not embodied in the rear axle but is ar- Specification of Lettersla'tent. Patentd Septfii, 1920. l V Original application filed June eigs s', Serial No, 305,725. Divided 'and th is application filed April,

The ends of the'axle 17 ,and the construe i tion employed at each end ofthe drive shafts i 19, andupon the. drivingwheel's 23, being exactlythesame, the description ofbutone will be sufficient.

I .lhe axle 17 is provided adjacent its end Withradial arms 20,terminating in their outer ends in'journals 21. The. end ofrthe axle is;provided with a stub axle 22 arranged,

centrally thereof and centrally disposed with regardto the journals, 210f the radial arms ,20.'- The's'tub axles '22 comprise tapered por- 1tions 22, formed on the o'uter end of the stub axles and'sti aightportions 22 fO1i d the axle 17 proper.

axle and has secured thereto by means of bolts 24 a plate 25 embodyingan outstand-g stub: axles next adjacent 1 t A driving wheel 23 isrotatably mounted upon the tapered portion 22v of the stub the radialarms 20, and is provided with a" driving pinion 28 having the teeththereof meshing with the teeth 27 of the flange 26. 'Mounted in theremaining journals 21 of vided with idler pinions 30, which also meshwith the gear teeth 27 of the flange 26.

It will be seen that the construction shown,

and thus far described will of itself support the driving wheels andprevent thrust by cause considerable wear in the journals 21 by the stubshaft 29, and thus allow of play which will cause the driving wheel 23to come loose and wobble. This wear I have eliminated-by placingabout'the portion 22 of the stubshaft 22, a gear 31 which meshes withthe pinions 28 and .30, eliminating the stress and strain placed thereonwhen the truck is running. 7

In actual practice at least three'of the radial arms 20, will beprovided, equidistantly spaced about the axle or an equivalent thereof.The pinions 28 and 30 support 8 5i i the radial arms 20 are stub shafts'29 prov the gear 31 in such a manner that it not v necessary that thesame befitted for rotation upon the stub axle but may be provided Withan enlarged central opening-afi'ordingspaces between the interior Wallthereof and the portion 22 of the stub axle 22, at 32 It Will be obviousto those familiar with ;shape,'-and size of'tho various parts beingzontal alinement-with the axle, a drive shaft mountedFin sa d last namedarms, driving obviously possible, I do not limit myself to theparticular construction hereinbefore set forth, but may make any suchchanges With- 7 v out departing from the spirit of the invention, or thescope of the subjoined claims.

What I claim is:

Q '1. Indriving gearing for motor vehicles,

an axle, a" driven heel, embodying spokes, mounted upon each end of saidax'1e,a plurality of arms mounted ad acent each end:

of said axle,one ofsaid'arms adj acent each end of the axle being insubstantially'horipinions mounted on the outer ends ofsaid 7 of saiddrive pinions.

Witnesses shaft, idler 'pinions mounted on theiother of SitlClPlIllOllS;and'aneinternally toothed gear carried 'byand arranged inwardly'of each.of sald drive wheelsiand" meshing with said pinions.
